HOISTING-MACHINE.

Specification of Letters Patent.

' Patented Mar. 9, 1215.

Application Med January 17, 1918. Serial Ho. 742,681.

To all whom it may concern:

. Be it known that I, FRED L. AnoUsER, a citizen of the United States, residing at Parkston. in the county of Hutchinson and State of South Dakota, have invented new and useful Improvements in Hoisting-Machines, of which the following is a specification. 7

This invention relates to hoisting machines to be used in connection with the storing of hay in a hay-mow or loft of a barn.

The primary object of the invention is to provide a hoisting or power transmitting machine whereby sufiicient energy or power, derived from an ordinary gasolene engine, is transmitted to suitable hoisting mechanism to enable the lifting or hoisting of hay from a. wagon up into the loft or haymow, thus obviating the necessity of employing horses or other animals heretofore almost universally used.

Another object of the invention is to provide suitable mechanism in connection with a machine of this character whereinthe energy or power, should occasion demand,

may be entirely cut oil at any moment without stopping or otherwise changing the speed of the engine.

A further object of the invention is to provide a simple and inexpensive hoisting machine, which is durable and reliable in operation and whichcan be manufactured and placed upon the market at a comparatively low cost.

With the above and various other objects in view the invention consists essentially in the provision of a suitable frame, upon which is mounted a roller or reel, the power or energy for operating the same being de rived from any adjacent source of power such as a. gasolene engine, such operation being conveniently controlled by a novel and peculiar clutch mechanism.

Certain other features of construction together with the combination and arrangement of the several parts'as will be hereinafter fully described and specifically pointed out in the appended clainr must be reasonably considered in determining the advantages and novel features of this invention.

In describing my invention in detail reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

. Figure 1 is a top plan view of the machine. Fig. 2 is a section on line 22 of Fig. 1. Fig. 3 is a detail view of the clutch mechanism.

Referring now more particularly to the drawings, wherein is illustrated the preferred form 'of my invention the numeral 1 designates the frame of the machine, mounted upon suitable wheels 2 and provided with the usual tongue 3.

While only the hoisting machinery has been illustrated in the drawings, the same is used in connection with any suitable mechanism generally employed for hoisting hay from a. wagon up into the left or haymow of a barn, such mechanism adapted to be controlled by a rope or cable 4 attached to a reel 5 revolubly mounted upon a shaft 6 journaled within brackets 7 secured to the frame of the machine. Each end of the reel 5 is Provided with an annular flange, the periphery of one of whichis provided with a plurality of notches 9, adapted to be engaged by a suitable pawl 10 pivoted as at 11 and controlled by a hand operated rod 12 slidably mounted as at 13 upon the frame.

the other end of the shaft is provided with.

a. suitable pulley 19 connected to any convenient source of power such as a gasolene engine (not shown) by means of a belt 20. By this arrangement it will be seen that the power for operating the reel is generated from the engine and transmitted through the medium of the mechanism just described.

The means employed for controlling the operation of the reel comprises a specially constructed clutch, composed of the above mentioned sprocket 15 which' is slidably mounted upon the end of the shaft 17 and provided with a collar 21 formed integral therewith. The said collar 21' has a notch 22 adapted to engage a pin 23 projecting from the shaft so that-the motion of the latter will be'imparted to the sprocket during such engagement between the pin and notch. A spring 24 is mounted upon the end of the shaft 17 and interposed between a suitable plate or Washer 25 and. the outer face of the wheel 15, this arrangement normally forcing the notch into engagement with the pin.

when it is desired that the shaft 17 be turned independent of the sprocket 15, the same may be accomplished by the operation of a suitable hand lever 26 pivoted as at 27 upon the frame 1 and pivotally connected as at 28 to a suitable yoke 29 adapted to straddle the collar 21 thereby slidin the sprocket according to the shifting or the said lever 26.

A guide 30 through which the rope l extends, is pivotally mounted upon a shifting member 31 in turn loosely mounted upon a cross rod 32 carried by standards 33 of the frame. During the Winding or unwinding of the reel the rope will necessarily move toward one or the other end of the drum, and it is to follow such movement that the member 31 is loosely mounted upon the cross rod 32. A connecting; rod as depends from the member 31 and normally fits within the forked end 35 of a hand operated lever 36 pivoted. as at 37 to the frame. manipulating the lever 36 according to the movement of the rope, the shifting of the guide 30 is permitted as desired. Any fastening element such as a chain 38 may be employed for holding the machine immovable during its operation.

The construction of the machine having been fully described, the operation thereof is as follows: The rope e is first attached to any suitable hoisting mechanism for raising the hay from the Wagon to the loft or haymow and the engine started, in which event motion is imparted to the reel, the winding or turning of which will wind the rope and cause such hoisting mechanism to operate. After raising the hay as desired the lever 26 is manipulated, thereby throwing; out the clutch mechanism and allowing the reel to unwind independent of any operation whatsoever, such unwinding being caused by the weight of the hoisting mechanism not shown. Should the weight of such mechanism prove insullicient to cause the unwinding of the reel the engine may be reversed and the clutch automatically thrown or slid by the tension of the spring thereby unwinding the reel in this manner. When the whole length of the rope is unnecessary for the operation of the hoisting mechanism, the reel may be stopped at any desired point by the operation of the hand rod 12, such operation causing; the pawl 10 to engage one of the notches 9 of the reel flange thereby limiting or stopping the turning of the reel.

From the above taken in connection with the accompanying drawings it will be seen that the operation of the machine is extremely simple; that the clutch mechanism is absolutely automatic and instantaneous in operation and that the substitution of an engine in place of the animal power pre-- viously used will prove a great saving, of both time, labor and expense.

it is thought from the foregoing" that the advantages and novel features of my de vice will be fully appreciated.

I desire it to be understood that 1' may make slight changes in the construction and in the arrangement and combination of the'several parts, provided such changes fall Within the scope of the sub ioined claim.

Having thus fully described my invention, what I claim as new and dem're to secure by Letters Patent, is:-

A hoisting machine including in com-- bination, a wheeled supporting frame, a reel mounted for rotation at one end thereof, means rotating said reel, uprights upon said supporting frame, a shaft connecting said uprights, the latter serving as a stop means,

a shifting member mounted for sliding movement upon said shaft, said shifting member being movable from one to the other of the said stop means, the said shaft being disposed in spaced relation to, at one side of, and above said reel, a guide member pivoted to depend from the free end of said shifting member, the element wound upon the said reel being adapted to extend through an opening in said guide. a rod depending from said shifting member at the opposite end thereof from that upon which the said guide member extends, said rod. be ing rigid therewith, an operating lever pivoted to said supporting frame and pivotally connected to said depending rod for shifting said guide member during an. unwinding or winding of the element upon the reels, and means actuatable to control rotation of the reel, as and for the purpose set forth.
